Hello FlexRadio enthusiasts! I am a computer science major at Groce City College in Pennsylvania working with my professor and a small group of engineering and computer science students. We are attempting to create a simple SDR package deployable on Windows CE/Pocket PC. The specific PDA we will be using, since one is readily available for testing purposes, is the Compaq iPaq 1940.
I've successfully used VS.NET 2003 to compile the FlexRadio project. We will be using the built in sound card of the PDA as the ADC. We then plan to take this digital data, extract the I and Q, and demodulate the signal. DirectSound will give us access to capture buffers of the sound card and we can work with the incoming data. Initially we want to get FM working and then possibly some digital modes that can work with the limited bandwidth of the sound card ADC and be useful in the emergency bands for first responders. However, the PowerSDR project is a little overwhelming. Ideally we would like to use the DttSP library and merely code a new GUI in C#. We are looking for a little guidance as far as what is necessary for a minimal implementation of the sort we are looking to accomplish. We were wondering if anyone had made any sort of further documentation other than what is provided in the source or if you could point us in the right direction as far as what calls to the DttSP DLL are necessary to get FM working. If you can not help but have questions about what we are doing feel free to ask. I can have my professor or engineering friends answer any questions I can not.
